This invention relates to new and useful improvements in spring catches for metal sash.

tpis one of the principal objects of our invention to provide for metal sash a compactl be brought out in the following specification` and particularly set forth in the subjoined claims.

In the accompanying drawing illustrating our invention Figure 1 is. a perspective view of our latch structure, showing the plunger in engagement with the keeper. Figure 2 is a longitudnal sectional view taken through the plunger barrel, showing how the plunger is engaged by the finger which is integral with the handle. Figure 3 is a cross sectional view taken on the line 3-3 of Figure 2, showing how the forked end of the handle lingerstraddles the plunger spring. And Figure 4 is a top plan view of the handle and plunger unit.

Referring to the accompanying drawing for a detailed description of our invention, the numeral 1 designates Ya barrel that is preferably rectangularin section and formed with two apertured side ears 2, 2 for attachment to a metal sash 3 by means of screws 4.

integrally formed with the front portion of the barrel 1 are two parallel outwardly projecting lugs 5, 5'. These lugs are formed with oppositely disposed holes to receive al transverse fulcrum pin 6 for` an enlarged portion of a curved handlev 7 Integral withv the latter below the pin 6 is a radial finger 8 terminating in a forked portion 9 which fits in a tapered or V slot 10 in a plunger or bolt llethatis preferably squarecross section.`

This plunger is free tomove longitudinally within abroached hole in thefbarrel 1 which is closed at itsrear end 4toprevent a protrusion of the plunger from that end. The plunger, however, does protrude from the front end of thebarrel to engage its Vbeveled end 12in a hole in a strike plate 13v of a keeper 14 secured to a frame 15 by screws 16.

engaging its rear wall, is a helical spring 17 Axially mounted within the barrel l, and

ical recessed part V19 of the front wall of the l plunger'.V The front end of thefspring engages this recessedfront part of the plunger to force the front end 12 of the latter into the hole inthe strike plate of thejkeeper 14. The forked portion 9 of the handle 7 straddles the spring 17 within the V slot 10 in the plunger so that when the handle is raised, the finger will engage the rear wall of the V slot to force the plunger .rearwardly against the compressed spring, to

withdraw the plunger from engagement with the keeper. The finger 8 being in one piece with the handle 7, conduces to a simple and durable construction that is made more coinpact by closing the rear endof the barrel against the protrusion ofthe rear end of the plunger.

the finger 8 on.

Having described our invention, we claim: Y

1. `A device of the-type described, comprising a barrel closed at its rear end, a plunger square in cross section in said barrel and free 'to move out of its front end, said plunger formed with an axial hole extending inwardly from its rear'e'nd to a point well near itsfront end, a V slot in the upper portion of said plunger opening into said axial hole, a

helical spring projecting from the rear wall of saidbarrelinto the axial hole in the plunger, ears projectingoutwardly from said barrel over the V slot, a handle pivotally secured between saidears, anda finger integral with the inner end of said handle and having a forked portion for entrance into said V slot io straddle-the spring'for the 2. A deviceof the type described, comprispurpose speciing a barrel closed at its rear end, a plunger in said barrel and free to move out of its Yfront end, said plunger formed Withan axial hole extending inwardly from its rear end to a point Well near its front end, said plunger also formed with Lebt-*opening into the axial hole, ya helical spring projecting from the rear Wall of said barrel into the axialr holein the plunger for eontactwith the front p Wall of the latter, arhandlepiwotally secured e tosaid barrel, and a forked portion on the inner end of said handle/orlgllrance into;
